BUILDING AND BRICKS THEREFOR.

Application filed November 25, 1922.

To all whom it may concern:

Be it known that I, EDMOND J OSEPH FRE- wnN, a subject of the King ofGreat Britain, residing at Terminus Chambers, 6 Holborn Viaduct, London,England, have invented new and useful Improvements in Buildings andBricks Therefor, of which the following is a specification.

This invention relates to bricks formed 10 on one face with portionslying in different planes and also with a cross piece forming twointernal cavities. The face of one brick interfits with a portion of thefaces of two opposing bricks so that the cross piece in the brick in onerow comes opposite the joints between two adjacent bricks in theopposite row.

According to one form of this invention a T shaped brick has a shallowstem and a cross piece, having two cavities. A wall made of two rows ofsuch bricks is so disposed that the pieces separating the cavities inthe bricks of one row are opposite to the joints between the bricks ofanother row.

T he ends or sides of the cross pieces and the stems may be grooved ordovetailed or rebated for the purposes of keying and/or fitting inmortar setting.

The accompanying drawings show walls and bricks made in accordance withthis invention.

Figure 1 is a section of a wall composed Serial No. 603,336.

of two rows of T shaped bricks having shallow stems. Figure 2 is asection of a wall made of bricks having two shallow stems.

Referring to Figure l, the wall is constructed of two rows of T shapedbricks a having shallow stems b and cavities b, the piece 0 separatingthe cavities being opposite the joint d between the bricks of the otherrow.

Referring to Figure 2, the bricks a have cavities b and two shallowstems e e which stems, when the bricks are assembled form the equivalentof the stems 6 shown in the other bricks, resulting in the wall shown inthis figure being equivalent to that shown in Figure 1. i

I claim as my invention:

1. A wall composed of two rows of bricks each having two cavitiesseparated by a central cross piece, and having an elevation and adepression on one face, each cavity extending into the opposingelevation.

2. A wall composed of two rows of bricks each having two cavitiesseparated by a central cross piece, and having two elevations on oneface, the cavities extending into the elevations.

In testimony that I claim the foregoing as my invention I have signed myname this 16th day of November 1922.

EDMOND JOSEPH FREWEN.
